UR-105TA Clockwork Orange

The UR-105 TA embodies all the years of research invested into URWERK’s wandering hour satellites. Here, the ingenuity of the mechanism lies in the invisible carousel responsible for the operation of the satellite hours. Four satellites made of aluminum and mounted on their own bronze/beryllium Geneva cross - all precisely cut on URWERK’s CNC machine tools - slowly orbit to display time. The hidden carousel has been treated with ruthenium then bead blasted to a finish meeting the very highest standards of haute horlogerie. Four satellites made of aluminum and mounted on their own bronze/beryllium Geneva cross - all precisely cut on URWERK’s CNC machine tools - slowly orbit to display time. Each satellite completes four 120° turns in the period between leaving the minutes arc and arriving again, displaying a new numeral. A circular canopy with openings highlights the current hour. Once the hour has elapsed, the satellite – guided by a Geneva cross – rotates as it continues its orbit for another three hours before returning to center stage. Each satellite indicates the time in both analogue and digital fashion as it arcs across the minutes chapter. This banana-shaped minutes chapter is satin-fnished and its numerals painted with orange Super-LumiNova®. The UR-105 TA Clockwork Orange features dual air turbines on full show on the back through two sapphire glasses in an impressive titanium body. These turbines are coupled with the rotor and adjust the speed of the winding ... in an impressive titanium body. system to minimise wear. The winding mode on the UR-105 TA is selected by a small lever in sandblasted and brushed titanium.The selector switch controls the amount of air escaping from the turbines. The bezel of the UR-105 TA comes in steel with a brushed finish. It will be treated with a PVD process to turn it black. Casing up of the movement. One of the final and most sensitive steps before a full week of testing.
